Sound link will not charge

Hi,

What happens if you use it until it only has about 10% -15% charge left?

Does it charge past 70% when you go to charge it?

If not, if it is an original battery perhaps it’s starting to fail. Even rechargeable batteries have a lifespan.

Here’s a link to the ifixit Bose SoundLink Mini 电池更换 guide.

Here’s a link to just one supplier of a replacement battery. Ensure to select battery model 061385

It’s not a recommendation to use them. It is shown to give an idea of the cost of the part. There are other suppliers online that may suit you better. Just search for Bose SoundLink Mini battery 061385 to get results.
